Note:
This
is
a
very
subjec.ve
pricing
based
on
the
standard
design
of
ready

tanks
.
To
get
a
more
accurate
pricing
based
on
a
specific
design,
it
will
require
some
.me,
not
un.l
the
end
of
holiday
on
the
11th.
The
making
charge
of
the
welders
will
vary
between
Dinajpur
and
Dhaka.
It
seemed,
this
par.cular
kind
of
metal
sheet
pricing
is
not
fixed
(open
for
bargain)
most
likely
because
this
was
not
a
standardized
industrial
product.

keeper
was
not
able
to
give
a
clear
answer
what
the

refers
to
and
what
the

was.
This
was
the
only
shop
open
due
to
the
holiday
therefore
was
not
able
to
verify.
